Detection of Upper Gastrointestinal (GI) Bleeding With a Novel Bleeding Sensor Capsule [DING]

Capsule is swallowed by the patient and an external study receiver records the capsule sensor data for 4 consecutive hours. Patients undergo endoscopy within 12 hours after capsule ingestion. Afterwards, the endoscopic findings (endoscopy pictures and patient's endoscopy report) are compared to the sensor capsule data results. Capsule excretion is monitored for up to 4 days. If excretion is not recorded during that time, a follow-up examination of the patient is conducted after 10 days.
